This patch introduces a sysfs group entry for the UFS attributes. The group adds "attributes" folder under the UFS driver sysfs entry (/sys/bus/platform/drivers/ufshcd/*). The attributes are shown as hexadecimal numbers. The full information about the attributes could be found at UFS specifications 2.1.
